we … The Pahari School of min…Great lengths of mountains, thriving ecosystems, the ever-spreading sky together with the lithosphere, hydrosphere and atmosphere create a saga called “Nature”. Rich both in terms of its scenic beauty and replenishing resources, nature accounts for supporting life in different shapes and forms on our planet.
Every member of the living world obtains its life support from nature. Nature guides the cycling of air, water and life between the different constituents or spheres on Earth. The treasures in nature not only provide for our basic requirements of survival but also fuel the raw materials to support factories and industries on which the modern world primarily runs.
Since the population is increasing at an exponential rate largely in India and many parts of the world, the “use” of resources has now turned to depletion. Adding to this, are the excessive levels of atmospheric and environmental pollution. Industrial wastes, unchecked use of vehicles, illegal cutting of trees, poaching of animals, nuclear power plants and many more are contributing to the disruption of the natural systems and global warming.Great lengths of mountains, thriving ecosystems, the ever-spreading sky together with the lithosphere, hydrosphere and atmosphere create a saga called “Nature”.

Industrial wastes, unchecked use of vehicles, illegal cutting of trees, poaching of animals, nuclear power plants and many more are contributing to the disruption of the natural systems and global warming.While it is necessary to keep up with industrialization, it is an urgent need now to restore stability in nature. People are trying to curb the level of pollution and stop the exhaustion of natural resources. However, more awareness and implementation is a must at the individual and community levels. We must always remember it is us who depend on nature for survival and not the other way round.
